f SHINGLE.

Application filed March 18, 1921. Serial No. 453,439.

To all 'whom z't may concern.' A

Be it known that I, NORMAN I. HARSH- BERGER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Shingles, of which thefollowing is a specification.

This invention relates to shingles, and more particularly t0 asphalt shingles which are -so formedthat certain exposed parts may be locked down on the roof by adjacent shingles, so that it is impossible for any portion of the exposed parts to be turned up by the-wind or by warping or in any other manner. One of the objects of thel invention is to provide shingles so formed that .they may be vconveniently interlocked when laid on the roof. While my invention is applicable to any form of interlocking shingles, yet, for the purposes ofy illustration, I have herein shown and described a form of shingle which is very similar to the shingle shown and described in my copending application, Serial No. 369,801, filed March 29, 1920, and reference maybe had to said application for such details with reference to said shingles as are not particularly applicable to this invention.

Of the drawings of this present application, Fig. 41 is a plan view of a single shingle,

which embodies the features of my inven-A tion; Fig. 2 is a section along the line 2 2 of Fig. 1; Fig. 3 is a diagram indicating` the manner in which the shingles are interlocked4 when placedpn the roof; and Fig. 4 is a plan view of a plurality of shingles properly assembled on the roof.

Although my invention is applicable to shingles of variousi other shapes, yet the shingles which I have illustrated herein Aare T-shaped and comprise a main or top portion 1() with the projecting or shank portion 11, the shank portion being that portion which overlies the adjacent shingles and the top `portion being covered by adjacent shingles. As the shank 11 is thus the exposed portion, and the portion most likely to become deformed, I form the shingles so that the corners 12 of the Shanks 11 are adapted to slip under the shoulders9 of the adjacent shingles. In order to lock the shanks 11 to the roof, bymeans of the corners 12, I prol vide slits 13`'inf-the shingles, arrangedlso that adjacent shingles. In laying the shingles the corners 12 are slipped under the respective shoulders 9 ofthe underlying shingles 14 and l5, by pulling each shingle 16 upwardly with its edges 17 passing into the respective slits 13 of the underlying shingle; and thus, when the shingle 16 is pulled upwardly to its proper place, the corners 12 will be locked firmly in place by the shingle-s 14 and 15.

It has been found, in laying ordinary shingles of this nature, that it is diliicult to slipi the edges into the slits, as they come in contact with the corners of the shoulders 9. To obviate this I press the shingles in any suitable manner so as to curve the corners of the shoulders 9 upwardly, as indicated in Fig.- 2. When the shoulders are thus formed the edges 12 may be pulled upwardly into the slits and under the shoulders very conveniently.

To further facilitate the passage of the Acorners into the slits I form the Shanks 11 so thatY their outer ends are wider than their inner ends, making the edges 17 rounded or slanting, so that they ,may pass into the slits gradually, having no corners at this point to come against the shoulders 9. In this way, with. the upturned corners described hereinabove, it is necessary only to place the shingle as indicated in Fig. 3, and pull it outwardly, and the slanting edges will pass into the slits until the corners 12 are properly under the respective shoulders 9. i

I claim as my invention:

l. A' plurality of shingles, each comprisinga top and an integral shank, the shank projecting from the central portion of one edge of the top and a corner projecting from each side of the outer end o-f each shank and adapted to lie under the top portion of the adjacent shingle of a roof, the edges of said Shanks being inclined.

2. A. plurality of shingles, each compris- 'ing a top and an integral shank, the shank projecting from one edge of the top and having corners at its outer end, said top having .slits in the edge from which said shank pro- 3. A plurality of shingles, each comprising a top and an integral shank, the sha-nk projecting from one edge of the top and having corners at its outer end, said top having slits in the edge from which said shank projects, each of said corners being adapted by means of said slits to pass under a portion of an adjacent shingle when laid on a roof, the projecting edges of said shanks forming acute angles with the edge from which said shank projects, the inner corners formed by said slits being turned upwardly.

4. An article of manufacture consisting of an asphalt shingle comprising a top and an integral shank projecting therefrom, the shank projecting from the central portion of one edge of the top, said top having a slit in its edge adjacent each projecting edge of the shank, the inner cornerA formed by each of said slits being bent upwardly.

5. A plurality of asphalt shingles, each of said shingles having a portion adapted to overlie a portion of an adjacent underlying shingle when said shingles are assembled on a roof, and a portion of said overlying portion being bent upwardly whereby said underlying portion may be more readily slipped under said overlying portion.

6. A plurality of shingles, each comprising a top and -a shank, the shank projecting from one edge of the top, and a lug projecting from each side of said shank, each of said lugs being adapted to lie under an inner portion of an adjacent underlying shingle of -a roof, one corner of said inner portion being bent upwardly.

7. A shingle, comprising a substantially flat body portion, a shank in the planeof said body portion and projecting outward from one edge thereof, said shank having locking tongues -on opposite sides of' the same and extending laterally outward therefrom, and said body portion having open locking slots on opposite sides of said shank at the base thereof, o-ne corner of said slots being bent upwardly.

8. A roof, comprising a plurality of shingles, said shingles having locking tongues and slots for interlocking the shingles together, the tongues becoming eng-aged with the slots on moving the shingles with the tongues relatively to the shingles with the slots in directions to cause the tongues to enter the slots, one corner of each of said slots being bent upwardly.

In testimony whereof, I hereunto set my hand.
